Be it known that I, JOSEPH F. MALONEY,

a citizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Air-Moisteners, of which the following is aspecification.

This invention relates to devices for supplying aqueous vapor to mixwith the combustible charges of internal combustion engines; and itconsists in the novel construction and combination of the partshereinafter fully described and claimed.

In thedrawings, Figure 1 is a side view of an internal combustion engineand a radiator, partly in section, showing moistening devicesconstructed according to this in vention. Fig. 2 is a sectional planview ofl Fig. 3 is a detail view in section of the cold air regulator.

The engine 2 is provided with an intake manifold 3 and an exhaustmanifold 4 of any approved construction. A radiator.5 such as ordinarilyused on motor cars is arranged at the front end of the engine, and has aspace 6 for aqueous vapor above its water space. A fan 7 of approvedconstruction is interposed between the engine and the radiator, anddischarges air rearwardly as indicated by the arrows in Fig. 1.

A funnel 8 for air and aqueous vapor is arranged on top of the exhaustmanifold 4., and is secured in position by any aproved fastening devicesor clamps 10. The larger end of the funnel projects forwardly of theexhaust-manifold,,and receives the air from the fanpwhich is revolved bythe engine. The smaller end of the funnel is connected to the carbureter12, which is 0 any approved flexible tube 14. The carbureter is con'nected to the intake manifold, and a regulator 13 is arranged to connectit with the flexible pipe 14. The regulator is tubular.

and it has lateral holes or openings 16 for the carbureter,

the regulator and 17 is a cylindrical slide on the which is slid backand forth to vary size of the air passage through the sai holes oropenings, or to close it altogether.

The funnel has holes or slots 18 in its underside for the admission ofhot air from the top surface of the exhaust manifold.

construction, by means of a A flexible pipe 20 is provided, and one endportion ofit is connected by a tubular'stem 21 with the vapor space 6 atthe top of the radiator.

The other end portion of the flexible vap or pipe 20 is secured in a lugor loop 22 1I1S1d8 the funnel at its larger end, and 24 IS a drain holefor water under the outlet end of the pipe 20. .The drain hole is formedin the funnel so that no Water which drips from the pipe 20 may find itsway into the carbureter. The funnel is conical from end to end, and ispreferably circular in cross-section, but it isnot necessarily circular.The hot air inlet extends longi tudinally along its bottom side, and itsbottom side is inclined downwardly toward the drain hole 24. Theflexible pipe 14 is connected axially to the smaller end of the funnel,and the larger end of the funnel is made relatively very large, so thatthe blast of air from the fan may force the mixed hot air and vaporthrough the funnel and down the pipe 14. Flexible pipesare provided sothat the various parts can be readily assembled together and applied todifferent makes of engines and motor cars.

The aqueous vapor thus introduced into the carbureter has a beneficialefiect in the engine cylinders, by decreasing the deposits of carbon,and in other ways.

What I claim is:

The combination, with an internal combustion engine provided with a fan,and a radiator arranged in front of the fan; of a tubular funnel adaptedto receive a blast of air from the fan, said funnel having its lowerside inclined downwar ly and forf wardly and provided with an inlet forhot air arising from the engine, a pipe for vapor communicating with thevapor space of the radiator, a fastening device securing the open rearend of the vapor pipe to the lower inclined side of the funnel at itsfront end so that condensed vapor may drip from the front end of thefunnel, and a delivery pipe for moistened and heated, air secured to therear end of the funnel in line the fuel intake of the engine.

In testimony whereof I have afiixed my d with its .axis and operativelyconnected with
